Owner`s manual

We recommend that you
clean the humidifier once a
week, or more often if you:
have hard water,
notice a build-up of
impurities, or
detect unpleasant odors.
It is normal for deposits
from tap water to collect in
the Remove and Rinse™
tray.
DO NOT USE SOAP,
DETERGENTS, OR
ABRASIVE CLEANSERS.
Cleaning involves two
steps: SCALE REMOVAL
and DISINFECTING. Be
sure to perform these in the
proper order to avoid
harmful chemical interac-
tions.
First, turn off and
unplug the humidifier. Wait
at least ten minutes for the
humidifier to cool.
Remove the No Drip™
water tank by grasping the
handle and pulling straight
up.

Never remove the Mist

difier has cooled.
MODELS DH-911/DH-912
Remove the Mist
Chamber by pulling out the
locking knob and
lifting up from the base

DO NOT clean the Mist
Chamber or heating ele-
ment under running water.
Doing so may cause dam-
age or personal injury.
Use a dry, soft cloth to
wipe the outer surfaces.
Step One: WEEKLY
SCALE REMOVAL
(Remove and Rinse™ Tray)
Lift the Remove and
Rinse™ tray out of the unit.
Fill the Remove and
Rinse™ tray with
DuraRinse™ Humidifier
Cleaner (#AC-816), follow-
ing bottle instructions, or
one 8-oz. cup of undiluted
white vinegar. Let solution
stay for 20 minutes.
With DuraRinse™ or
vinegar still in the tray,
clean all interior surfaces
of the tray with a soft
brush or cloth to remove
scale.
